The corresponding angles postulate states that if two parallel lines are cut by a transversal, then the corresponding angles are congruent.

Answer:

5/9

Step-by-step explanation:

If a variable y is directly proportional to x, then;

y = kx where;

k is the constant of proportionality

Given the expression y = 5/9 x

On comparing with the general formula;

kx = 5/9 x

k = 5/9

Hence the constant of proportionality of the expression is 5/9

Answer:

9.6 ounces

Step-by-step explanation:

Step 1

We find the amount of ounces of Almonds

Total amount of nuts in the container = 24 ounces

0.20 of the nuts are almonds.

Hence,

The amount of almonds = 0.20 × 24 ounces

= 4.8 ounces

Step 2

We find the amount of ounces of hazelnuts

Total amount of nuts in the container = 24 ounces

0.20 of the nuts are hazelnuts.

Hence,

The amount of hazelnuts = 0.20 × 24 ounces

= 4.8 ounces

Step 3

Therefore, the total amount of almonds and hazelnuts in the can is

4.8 ounces + 4.8 ounces

= 9.6 ounces

The given problem states that x and y vary inversely, and by using the given values, an equation is formed (x * y = 9) which can be used to find y when x = 3 (y = 3).

Since x and y vary inversely, we can write the equation as x * y = k, where k is a constant.

Using the given values x = 1 and y = 9, we can substitute them into the equation to find the value of k:

1 * 9 = k

k = 9

Therefore, the equation relating x and y is x * y = 9.

To find y when x = 3, we substitute x = 3 into the equation:

3 * y = 9

y = 9 / 3

y = 3

So, when x = 3, y = 3.

EXPLANATION

Since there are 11 males and 9 females out of wich 1 male and 1 female is to be selected.

The number of ways to select 1 male from 11 are 11C_1

The number of ways to select 1 female from 9 are 9C_1

So, the number of ways to select 1 male and 1 female is:

n = 11C_1 x 9C_1

n = 99

Answer: This can be done in 99 different ways.

Answer:

Step-by-step explanation:

9x - 7y = 24

3x + y = -2

9x - 7y = 24

-9x - 3y = 6

-10y = 30

y = -3

3x - 3 = -2

3x = 1

x = 1/3

(1/3, -3)

The lines 9x – 7y = 24 and 3x + y = -2 intersect at (\(\frac{1}{3}\), -3).

That is the common point, from where both the lines passes through at the same time.

Given lines:

9x – 7y = 24 (say eq. 1)

and 3x + y = -2 (say eq. 2)

Multiply eq. 2 with 3 and then subtract from eq. 1 :

Multiply eq. 2 with 3

⇒ 3 x (3x + y = -2 ) = 9x + 3y = -6

subtract eq. 2 from eq. 1:

9x – 7y = 24

- (9x + 3y = -6 )

= -10y = 30

or y = 3

put y = 3 in eq. 1, we get:

9x -7 (3) = 24

9x = 24 - 21 = 3

x = \(\frac{1}{3}\)

Hence the intersection point of both lines is (\(\frac{1}{3}\), -3).

Step-by-step explanation:

The measure of side c if a is 5 cm and b is 9 cm in a right triangle is √106 cms.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between the three sides of a right triangle in Euclidean geometry. The size of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides, according to this rule.

The measure of side c if a is 5 cm and b is 9 cm in a right triangle will be,

c² = 5² + 9²

c = √106 cms

The amount of each payment to be made into a sinking fund earning 8% compounded monthly to accumulate $57,000 over 8 years is $505.45.

A sinking fund is a fund that an organization or a government sets up to help repay its debts or cover its planned expenditures. It is also referred to as a reserve fund. The purpose of a sinking fund is to make payments towards a debt, such as a bond issue when it becomes due. A sinking fund helps reduce the risks associated with default. Sinking funds are used to pay off debts, replace assets, or fund upcoming capital projects.

What is Compounded Monthly?

Compounded Monthly is when interest is paid on the original principal as well as on the accrued interest. In simple terms, Compound interest is the interest that is earned not only on the original deposit but also on any interest that has already been earned. The monthly compounding formula is calculated using this method.

What is the amount of each payment to be made into a sinking fund earning 8% compounded monthly to accumulate $57,000 over 8 years?

To find the amount of each payment to be made into a sinking fund earning 8% compounded monthly to accumulate $57,000 over 8 years, we use the formula:

PMT = FV([i/12]) / [(1 + [i/12])^(n*12) - 1]

where,

PMT = Paymenti = Interest rateFV

= Future value of the investment = number of years.

In this case, the amount of the payment that needs to be made into a sinking fund can be calculated as follows: Let's first convert the interest rate to

monthly interest rates = 8% / 12 = 0.6667%

FV = $57,000n = 8 years

PMT = 57000 / [(1 + 0.6667%)^(8*12) - 1]/ [0.6667%(1 + 0.6667%)^(8*12)]

PMT = $505.45

Hence, the amount of each payment to be made into a sinking fund earning 8% compounded monthly to accumulate $57,000 over 8 years is $505.45.

(a) The utility function u(c, l) = log(c) - l represents a person's preferences for consumption (c) and leisure (l). The logarithmic term log(c) indicates that the person derives satisfaction or enjoyment from consumption. A higher value of c leads to greater utility, suggesting that the person likes consumption. On the other hand, the negative term -l represents disutility or a cost associated with engaging in labor or reducing leisure time. The person values leisure and would prefer to have more of it. Overall, the utility function balances the desire for higher consumption with the cost of reduced leisure.

(b) To find the equation of an indifference curve given a level of utility I, we set the utility function equal to I and solve for c in terms of l. The equation is:

I = log(c) - l

(c) The Marginal Rate of Substitution (MRS) represents the rate at which a person is willing to trade one good (leisure) for another (consumption) while maintaining the same level of utility. It is calculated by taking the derivative of the utility function with respect to leisure and dividing it by the derivative with respect to consumption:

MRS = ∂u/∂l / ∂u/∂c

For the given utility function, the MRS is constant and equal to 1. This implies that the person is willing to trade one unit of leisure for one unit of consumption, maintaining the same level of satisfaction.

(d) The optimal consumption-labor choice can be determined by maximizing utility subject to constraints, such as budget constraints or time constraints. Without additional information or constraints, it is not possible to precisely plot the optimal consumption-labor choice on a graph.

(e) To find the optimal amount of consumption and leisure, additional information or constraints are needed. The values of h (hours available for labor) and π (income or wage rate) would be necessary to consider the budget constraint. Similarly, the value of T (total time available) would be needed to account for the time constraint. Without these constraints, it is not possible to determine the optimal consumption and leisure levels.

Note: Please provide the missing values of h, π, and T to proceed with the calculation of the optimal consumption and leisure levels.
